The Dirty Dozen list of produce items with the highest pesticide residues that comes out annually included kale this year — the first time in a decade that the beloved leafy green has made the list.
Strawberries and spinach topped the ranking, respectively, while kale came in third.
The Environmental Working Group (EWG) bases its list on yearly reports released by the U.S. Department of Agriculture's Pesticide Data Program. It ranks produce items with the most pesticide residue levels, and includes the “Clean Fifteen” list of items with the least amounts of contaminants.
As part of the USDA’s testing, more than 92 percent of conventionally grown kale samples demonstrated at least two or more pesticide residues. Some had residue from as many as 18 different pesticides.
